To all whom it may concern: v I

lie it known thatJ, (imam: ,l. (imrrrrna, a citizen of the United States, and a resident of Woodstock. in the county of Ale-- 5 lleur v and State of Illinois, have invented certain new and uaeful Improvements in Auxiliary Sup rts for'Type-Writer'Shift- Frames; and do hereby declare that the following is a full, clear. and exact description thereof, reference being laid to the accompanying drawin s, and to the letters ofrelerence marked tiereou, which form a part 0 this specification.

This invention relates to a tvpewriting machine shift-frame, upon which the carriage iaoyupported and hascndwise movement, andwhich itaelf has haekwardand forward uhifting lll0\'0ll|t'llt ll[)0l) the machinc'frame in order to brung the platen and the paper thereon in ition to receive 'impmniona from. a plura ity of types carried by each of the type-bars of the machine. p

The invention is more particularly applicable to machine; of the, "Oliver" t v re. in which the shift-frame ia provided wit l two horizontal. -tranaversely arranged guidebara. on which the papebcarriune rests and -travels and in which said tide-bars projcct. at their. ends'heyond tie shift-frame proper and extend laterally outside of the frame 0! th machine and are made of anilicient length to properly support the carriaue. whatever may he the length of the at latter.

- The object of the invention is to provide means adaptad to afford proper support for nan kngtl of the aide-bars in auch. an in the I at) caae at extra ong carriages used for vcrv ide-iiars'in Machines in which the a t l Letters Patent Number 004,207. granted be Xuvcmlwr 17th,

in the drawings:-Figure lis a top plan view of an ()liver t vpewritiug machin together with a base hoard upon whit-1 it Penis. with my ilupmvementattached, with the paper carriage removed to show the 00 shift frame and its guide-bars. and with the type-bars and associated parts above the level of the shift-frame omitted. the sup- |mrtingstamlal1ls for the type-bars being shown in section. Fig. 2 is a vertical sec- 05 tion through the machine on an enlarged scale. taken on line 2-2 of Fig. 1. F ig. 8' is a partial \ct'ticnl section through Fig. 1 on th line 3-3 thereof, the sectional view being shown on an enlarged scale. Fig. 4 7 is a vertical ML'ilUll through Fig. 8 on the line 4-4 thereof.

As nhown in said drawings, 1 indicates the base-plate of the ty writing machine, 2. the pa mr-can-ia an 3. the shift-frame, which is sup 10116! on the base frame ao as to have -bae ward and forward shifting movement thereon, and is rovided with forward and rear. horizontai: transversely extending guide-bars 4 and .5, on which rent and travel the grooved sup rting pulleya 0, 7 of the carria e. Said shi -framo8 is supported at its orward end by means-0t pivotnll connected it right arms or links 8 8 whici are pivota ly at ndod 'hom the standard 9 rising from t base-plate,'aud at itn rear end by meana of a horiaontal ide' stem 11 rigidly attached to the ahit'trame and passing through a guide standard 12 on the rear of the base frame 1 and reatin k t iron a guide roller 18 mounted in the atant a 12.

In the machine illustrated, the pa ier-caririage 2 is made of considerable lengt in order to receive a very widesheet of paper and the guide-barn 4, 5. in order to 'roperly imp-Q port said carriage when moved to the limit of its e'ndwine movement in either direction.

are extended a considerable distance bedyond or outside of the base plate 1 at both ai e8 of the machine. The ends of said guide-bani arecach sup mrted from a horizontally arranged base board 15, on which the base 1 is centrally llis|msctl, hy meant-tot fixed members 16 secured to the lame board and oscillating'supporting arms 17 resting on said fixed members. Each oscillating arm 17 has pivotal connection with its associated glutlemt so as to swing transversely of the sluttframe. and hearing engagement with its 1908, to Theron It. Knapp. i fixed member 16 by meana of horimntally no es cameo separated iiet-icrewa l7 1?", no no to afiord rnn'ng'end fallin'g movement. of the end of the guide bar to correspond with the nunp/ and falliu movement, of the forward an of the nhii t-frnme as the links 8 are t ming on their suspension axes in the shifting movement of the shift-frame.

v lOl'IlS of an Oliver typewritiug The parts thus far brietly deneribed are substantially as shown in the patent above referred to, Number 004,20 form no part of this'invention, require no further desert tion.

18, 18 are aternlly disposed, horizontal logs or projections preferably formed in,- tegral. with the base i. andoc 'tionusually occupied by the car ing i mac tne. Each of said lugs is provided with means for enpportin the front guide-bar 4 at a point inter-met iateita outer end and its connection with the shift-frame. Said means embrace the followin': The outer end of each log 18 is faced o in a vertical plane to receive a vertical plate It) which is secured to it in any of aenews 20.

21 is a short rail or track, extendin in a directiontransveme to that of the at a bar t. Said track in spaced from sai plate 1'9 by means of a a acing washer 22, and. is

connected thereto w means of arrears 23, 23-

uhich are threaded into the plate 19 and paw through riotn 2t. 2t t'arnnrd in the rail 13!. 4h waiher 23" is inter wee-d between, the heads of mid screws and t w fare of the rail 21 to cover said slots and give hearin for said heads. Upon the up ier edge 0 said rail is adapted to rest llllt v rolla roller 25 rotatably mounted on a stud 26 which has mrew-threadml connection to an angle bar 27 secured to the guide bar 4. As the guide bar 4 is shifted forward and backward with the shift-frame, the roller 25 travels forward shifted forward and and backward on the rail .21 which thus farnishes an eiticient 'support for the guide-bat" at this point.

In order to aeconuumlate the rite and fall rail, due to tin-rise and fall of the slntt-truna- 3. as itv m'iugza forward and backward'with the links i the up ier ed of the rail 21 in curved trannvem-iy direction of the guide-bar 4. beinghi It'l at its ends anddepresaal at its nndd c, said curvature eorrea ionding to the curve in which the pivotal connectionaof the links 8 with the shift-frame travel as said frame i-z backward. By mam] of the slots 24, mid rail may be aecnnzteiy adjusted so as to give support for Main) roller .25 in eaehpoaition of the guide bar 1 c aim, all my nven ion machine frame, a 1a\per-carrin m, a shi .rame having shifting movement on the ma- 7, and as they.

ated in'- the to tie e combination with a typewritintr with a gut ohmr, aupporting armn for the shift-frame pivotully connected with the.

machine frame above the shifl-frame, lll'i means for supporting the cndaot said guidebar, of intermediate supports for said guidebar embracin laterally dixposed in made rigid with mud rted on vaaid'luga extending in a direction mnnverae to the lengthvof .said guide-bar. and parts carried by said guide-bar adapted to rent and ride on said tracks, said tracks being carved to afi'ord riam, and falling movement otsaid tide-bar men said arma are swung forwa ly and bmclrwardly from the central position thereof.

2. The combination with a typewriting machine frame, a paper-carriage, a shif ,frnme having shiftin movement on the machine frame, said s ift-framc being provided with a guide-bar, supporting arms for the shift-frame pirotally connected to the machine frame above the shift-frame, and

means for nupporting the ends of said guideconvenicnt manner as by mean-i -ba r, of intermediate aupporta for said guidebar emhraein rigid with said machine frame, tracks supported on said lags extending in a direction rnnnverse tothe length of said guide-bar, and rollers carried by said guide bar adapt- -cd to rest and roll on said-tracks, said tracks being! curved to anord rising and failing' movement ot" t tli i guide-bar when fluid arms are :swunp forwardly ant. liackwnrdly from the central position thereof.

3. A support for a shift-frame guide-her embracing, m combination with the machine frame, a laterally disposed lug made rigid with said machine frame. a. rail carried by amid lug extending in a direction transverse to the direction of said {aide-bar, said rail being curred horizontal y, and a part earned by said guide-bar adapted to rent and ride on said rail.

- 4. An auxiliary nupportfor n shift-tremeguidedmr comprising. Ill combination with the machine frame, a laterallv dispoeed inn formed integrally with said frame. a vertical plate necuret to Raid log. a rail spaced from and rigidly secured to said plate. mid

rail extending in a direction ltllltrlt'tm to the direction oi the in) h of said-goidc-bar and being curved horizoutallv, means for adjusting the position ioller carried by mid. guide-bar adapted to rest and roll on said rail.
